I ATTACHMENT FOR HOT AIR PIPES OR THE LIKE Filed Jan 20, 1928 PatentedJan. 7, 1930 UNITED STATES PATENT OFFICE CLARENCE GEORGE MOORE ANDCLAUDE MOORE, F INDIANAPOLIS, INDIANA ATTACHMENT FOR HOT-AIR PIPES ORTHE LIKE Application filed January 20, 1928. Serial No. 248,259.

This invention relates to attachments for air pipes and registers andthe like, and one feature of the invention is the provision of a screenstructure so arranged that it will prevent articles from descending intohot air pipes when properly arranged in the register associatedtherewith, orin the end of the pipe.

A further feature of the invention is in so arranging the same that itmay be used in connection with a pipe entering through the floor or wallof a building.

A further feature of the invention is the provision of means forreinforcing the edges of the attachment to protect it from destructionand to hold it in rigid position.

A further feature of the invention is the provision of means for readilyintroducing or removing the attachment from engagement with the pipesand registers. 7

Other objects and advantages will be hereinafter more fully set forthand pointed out in the accompanying specification.

In the accompanying drawings which are made a part of this application,

Figure 1 is a plan View of the attachment.

Figure 2 is a perspective view thereof and,

Figure 3 is a sectional view as seen on line 33, Fig. 1.

Referring to the drawings, 1 indicates a section of woven wire,preferably galvanized, the mesh of which is of such size as to preventarticles passing therethrough and entering a pipe (not shown) beneath orin the rear thereof, at the same time permitting a free flow of airthrough the register (not shown) normally placed over the end of thepipe.

Surrounding the edges of the section of wire 1 is a reinforcing means 2,preferably in the form of a channeled frame, into which the 4 selvageedges of the wire section 1 are secured, said frame being shaped to fitthe register box (not shown) or the mouth of the pipe over which it isplaced.

In order to readily introduce the attachment into position or remove thesame therefrom, handle members 3 are attached to the section of wovenwire in any approved manner, so that they may be grasped for transporting or otherwise handling the attachment.

Some forms of register boxes or pipes, especially those placed in thewall of a building, require means for retaining the attachment in properposition, and to this end stay wires 4 are connected to the woven fabric1, one end of the wire being passed through the wire fabric,-and thisportion then bent'along the face of the fabric a distance, the extremeend thereof being again passed through the fabric and crimped over theopposite face thereof, as indicated at M Fig. 3. The unsecured portionsof the stay wires 4 are extended outwardly a distance from the face ofthe woven wire fabric 1 and the extreme outer ends thereof then extendedat right, angles to form means for holding the attachment in properspaced relation with the end of the pipe over which it is placed and theregister cooperating therewith.

In applying the attachment the register is first removed from theregister box and the attachment then introduced over the end of the airpipe entering the register box, after which the register is returned toposition over the box and secured thereover in'the usual manner. Themesh of the fabric 1 is sufficiently small as to prevent objects passinginto the pipe over which the attachment is placed, but permitting freeflow ofthe heated air therethrough.

The stay wires 1, when used, rest against the inner face of the registeror the box in which it is placed and consequently retains the attachmentin close proximity to the end of the pipe, this being expresslyapplicable to wall registers where the attachment rests in a verticalposition.

What we claim is:

1. An attachment for hot air pipes or the like comprising a section ofwoven wire fabric adapted to be positioned over the end of a pipe, achannelled frame surrounding the edges, of the fabric, and stay wireshaving one portion extended parallel with one face of said fabric andresting thereagainst, said paralleling portion having right angularlyextending portions at its ends and projecting through said fabric, oneof which is bent over and engaged with, the opposite face of the fabricand the other extended a distance 'be- L100 yond the face of the fabric,said extended portion having a laterally extending end adapted to engagean object and hold said attachment in fixed position.

2. An attachment for hot air pipes or the like comprising a section ofWoven Wire fabric adapted to be positioned over the end of a pipe, achannelled frame surrounding the edges of the fabric, and stay Wireshaving one portion extended parallel with one face" of said fabric andrestingt he'r'eagainst, said paralleling portion havingright angularlyextending portions at its ends and projecting through said fabric, oneof which is bent over and engaged with theopposite face of the fabricand the othergextendeda distance'beyond the face of the fabric, saidextended portion having a laterally extending end adapted to engage anobject andhold said attachment in fixed position, and handle I membersattached to the fabric, whereby the attachment may be readily applied toor removed froln position; I v H CLARENCE GEORGE MOO E.
